pagination 'add_args'

Hi there,

I’m using ‘add_args’ to append a couple of vars into my pagination links.

The code looks like this:

function my_pagination()

{

    global $wp_query;
    $big = 999999999;
    unset($urlArgs);
    $urlArgs = array('searchBar' => $_REQUEST['searchBar'], 'searchType' => $_REQUEST['searchType']); // add args for search/filter

    echo paginate_links(array(
        'base' => str_replace($big, '%#%', esc_url( get_pagenum_link($big))),
        'format' => '?paged=%#%',
        'current' => max(1, get_query_var('paged')),
        'total' => $wp_query->max_num_pages,
        'add_args' => $urlArgs

    ));

}

This works fine for the first page of results (all the pagination links are correct e.g: /page/1?searchBar=40&searchType=18)

However if I click onto page 1 or 2 of the results all the pagination links become malformed with an extra parameter on the end (e.g. /page/1?searchBar=40&searchType=18#038;searchType=18)

For some reason the searchType parameter is being added twice but I’m not sure where it’s coming from or why.

Would be most grateful for any insight.

Cheers.
